John Thompson is a historian and a retired teacher in Oklahoma. He is also a meticulous researcher. Emily Oster is an economist at Brown University who said early in the pandemic that it was safe to open schools.

John Thompson: COVID and Schools
John Thompson takes a look at Emily Oster’s crusade to get school buildings open.
He writes:
When I started following Emily Oster’s links and critiquing her analyses of COVID in schools, I first worried about her simplistic conclusions such as, “The evidence is pointing in one direction. Schools do not, in fact, appear to be major spreaders of COVID-19.” Since Diane Ravitch posted on epidemiologists Abigail Cartus’ and Justin Feldman’s research, I better understand where Oster was coming from, and how “Oster’s emphasis on individualism and personal choice ring sweetly in the ears of the rightwing philanthropists.”
Oster went “viral” when arguing that educators’ fears were “overblown,” and that kids are “simply very unlikely to be infected.” But, as she made those claims, Oster ignored evidence that schools were significant spreaders, such as the CDC’s summaryof Wisconsin infections from Sept 3 to Nov16, 2020. That state’s schools were the 4th largest source of infections, following long term care and corrections facilities, and colleges; an estimated 14% of infections were linked to schools.
On the eves of Thanksgivings, when common sense said that holiday surges through Christmas and the New Year would be inevitable, Oster would double down on attacks on educators for not immediately reopening classrooms.As Rachel Cohenexplained, Oster’s 2020 data “reflected an extremely small and unrepresentative sample of schools.” There was not a single urban traditional public school reporting data across 27 states in her dataset, including from Florida [and] Texas…” Then, in November, Texas became the first state to have a million infections.
Worse, Cohen reported, “Rebekah Jones, a former Florida Department of Health data scientist who says she was fired in May over a refusal to manipulate her state’s COVID-19 stats, has publicly pushed back on Oster’s claims.” Jones “offered Oster full and free access to their data. ‘But she [Oster] basically decided to just pick what data she wanted, not what’s available.’” Jones added, “‘It’s offensive to researchers, when you see something so unabashedly unscientific, and when the opportunity to do something scientific was there.’”
Before long, I worried that Oster, an economist, was following in the path of economists who didn’t know what they didn’t about public schools and didn’t listen to educators regarding the flaws in their data-driven corporate school reforms. For instance, Oster seemed to disregard about 20% of the U.S. population [who] lived in homes with at least two adult generations or grandparents and grandchildren under 25 in 2016, according to an analysis of census data by the Pew Research Center. And the dangers of spreading COVID from students to older family members was greater in low-income Black and Brown households.
Also, Oster ignored qualifications made by researchers, such as the Duke University study finding that masks can minimize the spread in schools. Inresponse to my questions on methodology, co-author Daniel Benjamin volunteered what it takes to safely reopen schools:
Is that there is 99% mask compliance for every person in the mainstream curriculum that steps on school property. It’s the mitigation strategies—distancing, masking, hand hygiene that are crucially important. If a school district does not do these things, they will likely make the pandemic worse by being open. This is why we don’t advise “you should open” or “you should go remote”…. It’s all about the public health measures.
At that time, I worried about Gov. Ron DeSantis and Oklahoma Gov. Kevin Stitt citing Oster while pressuring schools to open up and drop protections. Neither did I understand why more journalists were not challenging her misuse of sources, and her repeated attacks on teachers unions, especially in publications funded by the Billionaires Boys Club. I sensed Oster’s methodology would cost lives. But, I didn’t want to prejudge researchers at a time when lives were on the line, so I didn’t connect the dots.
But Cartus and Feldman connect the dots and write about Oster’s important role in making:
The “data-driven” case for peeling away successive layers of COVID mitigations: first ending remote instruction in favor of hybrid learning, then ending hybrid learning in favor of a full return to in-person instruction, then eliminating quarantine for those exposed to the virus. … Her vision for schooling during the pandemic ultimately involves abandoning universal public health measures altogether, turning masking and vaccination into individual, personal choices.
Cartus and Feldman address my question why her work “attracted little scrutiny.” It was more than journalists and experts being unaware of the differences between the highest poverty schools and the schools their children attend. Most importantly her work:
Has been funded since last summer by organizations that,without exception, have explicit commitments to opposing teacher’s unions, supporting charter schools, and expanding corporate freedom. In addition to grants from the Chan Zuckerberg Initiative, the Walton Family Foundation, and Arnold Ventures, Oster has received funding from far-right billionaire Peter Thiel. The Thiel grant awarded to Oster was administered by the Mercatus Center, the think tank founded and financed by the Koch family.
Cartus and Feldman went deeper than I did in explaining the damage that Oster prompted. For instance, in her “2020 article in The Atlantic, ‘Schools Aren’t Super-Spreaders,’ Oster “assured readers in no uncertain terms that COVID transmission simply did not occur in schools at a rate that would necessitate closures.” But the analysis underlying the piece “drew on a sample of miniscule size—a mere two weeks of school data, reported in the second half of September 2020.” The sample was also biased by the fact that it was collected only from schools voluntarily participating in the Dashboard.
Cartus and Feldman then noted what so many journalists ignored, “The second half of September 2020 coincided with the very beginning of a national uptick in cases that would eventually become the punishing surge of winter 2020-21.”
When the press mostly failed to investigate the red flags that Oster’s work should have raised, “it became an article of faith that the laws of physics governing viral transmission don’t apply to schools, even as evidence of in-school viral transmission has mounted throughout the pandemic.”
Oster et.al’s “declarations of victory ignore[d] a growing body of research that has found schools contribute substantially to community coronavirus transmission, especially in the absence of adequate mitigation. The proclamation of “choice” that she justifies is really:
The ‘choice” to cast off obligations to others: the permission she offers affluent parents to disengage from the social contract. While the privileged seek a return to normalcy—or some sicker, poorer approximation of it—COVID will continue to infect and kill the working class and people of color at disproportionate rates.”
Now, history may be repeating itself. To quote National Public Radio, “People say they are done with COVID, but COVID is not done with us.” When we take stock of the interrelated harm done by anti-vaxers, anti-maskers, rightwingers, and their funders, as well as mistakes made by the CDC, we must draw upon Cartus’ and Feldman’s first draft of the history Emily Oster’s stardom.

———-
Good comment. Oster is an educated person with impressive credentials, but her notions help fuel an individualistic response to a mass crisis. Isn’t she the economist who recommends the spreadsheet approach to rearing children? She just doesn’t understand how many people live—multigenerational families, for one example.
Reminds me of a paraphrased line from a novel: He had gone through hell and knew a lot, but that didn’t make him any wiser. And another: “You could tell by the way he talked, though, that he had gone to school a long time. That was probably what was wrong with him.”
Some of the most educated people I know are incredibly ignorant and sure of their infallibility.
In fact, Oster has UNimpressive credentials — she made similar completely wrongheaded claims – FOR YEARS! – in her doctoral thesis, and got championed by similarly wrongheaded privileged people who loved her wrongheaded conclusions. Back when Oster was first getting publicity and praise for the completely wrong “data based” conclusion in the her doctoral thesis, there were many far superior scholars who tried to tell Oster she was wrong and provided detailed evidence that supported their warnings to Oster that she was making outrageously unsupported claims with her faulty data. But Oster continued to claim her data was excellent and blew off everything her critics said. After all, what did it matter that some non-Ivy League academics had some data she had no time to bother looking at, when so many folks who were in a position to advance her career loved her conclusions so much. Oster isn’t just privileged herself, she is savvy privileged and knows exactly who is important to please and who can be disregarded.
Why would Oster care about how her faulty conclusions affect low-income kids in overcrowded, underfunded urban schools who live in multigenerational and crowded homes? She speaks to the privileged folks who have multiple bathrooms, extra bedrooms, and know their family will be first in line to access medical treatment when hospitals are to inundated that multiple refrigeration trucks are used to hold all the dead bodies. But she is doing it “for the kids” she says. She has the data, she says.
I have no doubt that years after this is over, long after Oster’s claims have done the damage they have done because she claims certainty when there is none, Oster will write some new paper that completely retracts everything she said. And get praised for that retraction.
One of the things that I find most disgusting about Oster is her response when she is challenged about the horrible things the right wing does citing her data. She whines that “she can’t help it” if they say that. She reminds me of Ivanka Trump and in fact she seems to have a very similar moral code to Ivanka Trump. It is always more personally rewarding to remain silent and complicit and then whine that it’s not my fault that you gave credibility to the people who needed you to legitimize the nasty things they do who cite your support. If Emily Oster actually cared that her data was being incorrectly used, she would speak out.
When you allow yourself to be used and then whine that it’s not your fault, you are Emily Oster and Ivanka Trump. No one told them they had to remain silent and complicit. They CHOSE to do so and expect the rest of us not to notice that it just happened to be far more personally rewarding to remain silent when their own self-interest was at stake.
^^Note that years later, Oster got praised for completely retracting the conclusions she presented as data-based certainties in her doctoral thesis.
Privilege. She didn’t get fired for all the years she disregarded everything the critics said and getting positions based on her stellar data-based research. She got praised when she finally admitted she was wrong long after her position was secure.
That’s privilege.
She as absolutely NO credentials in epidemiology, which is the relevant area of expertise when it comes to COVID and school safety.
Some economists believe that just because they know how to feed data into a statistics package, that makes them a legitimate analyst in any subject they focus on.
That’s just bullshit.
And why ANYONE would listen to an economist on epidemiology is a complete mystery buried in an enigma wrapped in an enema.
I know many epidemiologists. Some are very good friends of mine. Oster is not epidemiologist.
Some second looks at the biggest “expert” saying Covid wasn’t spread in schools. The reality, and who funds her research.
>
The “amnesia strategy” is obvious. What will thinking people and Democrats do other than point to the accurate documented history, as has been done for January 6. Or anything else that was yesterday’s scandal that Democrats let republicans conveniently forget and reframe for their ideological fascist purposes.
Oster is not a scientist, which she demonstrates very clearly by her approach to scientific issues.
The worst part about Oster is not even that she turned out to be wrong about the infection and spread of SARSCOV2 by young (school aged) children
It’s that she had decided that even the risk of children getting infected was very low (“very unlikely” is how she put it) BEFORE anyone — including herself, not incidentally– had anywhere near sufficient data to draw such a conclusion.
Back on May 4, 2020 when the data on how the virus spread were still extremely limited (almost non-existent might be a better description) Oster was already assuring parents that
“In practice it seems that infection among kids is simply very unlikely. It’s not that they are infected and don’t know it, it seems like they are just not infected very often. And when they are, it may be that the mild symptoms limit their viral spreading (like with the kid in the French example). ”
That proved to be demonstrably wrong.
Her entire “schools are safe” schtick was the epitome of motivated reasoning from very early on.
And to top it all off with a cherry (which Oster clearly loves) , she wrote an article in the Atlantic pleading for amnesty and forgiveness for everyone who was wrong — which doesn’t include her, of course.
“Amnesty” according to Emily Oster: “Admit you were wrong!”
“Economist turned COVID-19 contrarian Emily Oster recently published an article in The Atlantic about offering amnesty and forgiveness over the pandemic. Shorter Oster: “Admit you were wrong!” — by Dr. David Gorski (aka Orac)
https://www.respectfulinsolence.com/2022/11/02/amnesty/
Gorski prefaces his piece with the relevant background:
“Before I discuss her “amnesty” narrative, one important thing for you to know about Emily Oster is that nearly her entire shtick about COVID-19 has been to minimize the danger of coronavirus transmission in schools, going back to very early in the pandemic. Indeed, as early as April 2020, she was penning op-eds doing just that, for example an op-ed in The Washington Post entitled Opening schools might be safer than you think, in which she argued that the benefits of in-person instruction were high enough to outweigh what she considered the relatively low risk of coronavirus transmission in schools, arguing that the data suggested that schools “might be one of the least risky kinds of institutions to reopen.” In another op-ed in The Atlantic entitled Schools Aren’t Superspreaders, in which she dismissively described fears of school transmission as “overblown” based on a grossly inadequate subset of her dataset.”
/// End Orac quotes
I would only add that Oster had actually reached her (clearly motivated) conclusions a full month earlier than Orac mentions – on May 4, 2020, when little was actually known about how the virus spreads — to say nothing about the role of children in it’s spread.
As I detailed in a comment in October 2020 in response to (another) BS article that Oster had published in the Atlantic

Data Driven
When data are driven —
Along for the ride —
They never are given
A chance to decide
Now tell us what you really think! I think I’m becoming data driven crazy. Oster means Easter in German. We definitely don’t need any resurrection of her ideas.
Strike my month earlier claim
May comes after April!!!
Good thing I am not debating with Gorski
Oster is neither a scientist nor an educator. What she is is a tentacle of the Kochtopus. I read that Charles is trying to rebrand as a neoliberal “philanthropist”. Oster is the perfect shill. She’s Michelle Rhee 2.0, no problem inflicting harm on children and teachers in the pursuit of cheaper human capital. Chucky Koch is throwing money and connections at her, and when people play with Chucky, people die.
Ms. Oster needs to follow:
Safe Open Schools Pledge
I,_____Emily Oster_________, will publicly commit seppuku or agree to be guillotined on the State House lawn when the first innocent childrens’ Covid deaths and co-morbidities obtain from the opening of schools without all of the proper health safeguards in place.
Utah’s K-13 schools went back full time in August 2020 and mask mandates were banned in spring 2021. The amount of COVID that spread through schools was crazy, even with masks. All 9 high schools closed multiple times and many junior highs and elementaries did as well. Several teachers died.
Our test scores still dropped.
The “Iowa Mama Bear” who is given partial credit for the Governor’s decision to end mask mandates in schools will be appearing in court. The allegation is she made false charges to DHS against a former associate.
Kimberly Reicks, mother of 7, is in the news this weekend, in articles with the headline, “Mike Flynn’s Cuckoo Circus.”
Reicks had received publicity for her scheduled speech at the Flynn Re-Awaken America tour.
That’s the 9 high schools ol is the district in which I teach. The comment got cut off.
Cherry picking data to manipulate perceptions of an existing crisis is very similar to verbal misinformation. The goal is to skirt the truth, and it is a typical strategy of liars that promote right wing ideology.
Unfortunately National Public Radio, which claims to have intellectual superiority relative to other media outlets, has uncritically accepted her views as authoritative.
NPR doesn’t like it when people refer to them as National Public Radio
As a former head of NPR once aptly said
“NPR stands for nothing”
She don’t know just how right she was.
Didn’t know
Personally, I prefer National Presstitute Radio.
They won’t say anything that upsets their “underwriters” — ie
the folks who pay their bills.
Really no different than any other corporate media organization.
Other than the fact that CPB gives grants to local stations who then use some of that money to pay for NPR programming and “membership dues”. So, even though this backdoor funding might amount to only about 8% of NPRs funding, they still DO get money from you and me, notwithstanding what NPR likes to claim.
I am thankful for Tiny Desk Concerts, however. Here’s a recent one from NoSo, a wonderful transgender artist who makes you forget about labels. The first song here is something special.
It wasn’t just NPR.
Oster was the darling of the mainstream media because they loved her confident stance, challenging as it did the traditionally reserved,uncertain stance of scientists who understand don’t like to draw conclusions without adequate data.
The media like simple concrete answers like “schools are safe”, not the sort of uncertain, tentative, caveat laden answers that scientists typically give: “school safety is community and school dependent. Whether a particular school is safe depends on many factors: community infection rate, safety precautions taken by the school, testing done within school and surrounding community, quarantining of infected students, etc”
Mainstream journalists at NPR and elsewhere started yawning the second they heard the latter.
The pandemic revealed a great deal about American “news” organizations and a lot of it was not particularly flattering.
“To quote National Public Radio, ‘People say they are done with COVID, but COVID is not done with us.’ ”
The pull quote from this post above explains why I’m done with my old habits and still isolating myself most of the time. When I do go out, I wear masks (plural), An N95 (I think that’s what the safer masks are called) and over that a cheaper mask (two layers). When I return to the car, I sanitize all my exposed skin.
I want to make a point so I’m going to share how much my life has changed, changes I plan to keep because I’m saving so much money staying home instead of going out to shop as much as I did before and eating out several times a week before the pandemic. If I eat out, it is take out (maybe once a month at most), and I eat in the car, not around idiots who are not wearing masks.
2022 (for 2020 and 2021, I seldom went out and had most of my supplies delivered. I avoided shopping in person and I stayed away from the VA medical clinic and the dentist. Because I avoided the dentist for two years, I paid for that later.)
January: I went out two times in 31 days. Once to the dentist and on the way home stopped at Trader Joes and Whole foods. The second time was to pick up a package at FedEx.
February: I left the house five out of 28 days (three of those trips were to the dentist).
March: Again five trips to the dentist (because I hadn’t been to the dentist for two years 2020 and 2021 until one of my crowns broke off leading to oral surgery and a lot of follow up work) and three times to the US Post office to drop of mail while avoiding those not wearing masks. That meant keeping more than six feet away from all of those idiots.
April: One dentist visit and two supply runs.
May: Three – one to the post office and two supply runs. (I started buying in bulk to cut back on being exposed to really stupid people that don’t wear masks or follow the six foot rule).
June: four – (one was to the post office and another one was to the VA for a visit to my primary care doctor and at the VA everyone is wearing masks or you can’t get in.)
July: three – all medical or dental
August: four – one to the VA, one to the Dentist and two supply runs
September: five – three to the VA, two dental
October: three – one to the dentist, one to the VA and one shopping run to buy supplies needed to replace the kitchen faucet. Not wanting to hire a plumber to do the job (meaning I’d be exposed to another person even if he wore a cheap mask that most people that still wear masks wear, cheap ones) I watched some YouTube videos and spend the day replacing the kitchen faucet by myself, and saved hundreds of dollars in the process.
November: three shopping trips to buy necessary supplies to eat, et al. by now, I’m seeing maybe one in twenty people in public wearing masks.
December: one full day spent at a hospital’s ER being tested to see if I was going to die or not (I’m still here), and two supply runs.
I don’t fear dying. Why worry about something we can’t avoid.
Instead, I’m really concerned about living with Long COVID!!!!!!!!!
I enjoy being healthy and having a rational mind that can actually reason and think. I don’t want to live out my last days mired in a “brain fog” with serious health problems due to multiple organ failures.
And every time we go out in public for any reason using a car with a gasoline engine, we burn fuel and contribute to global warming and climate change. I used to fill my tank every two weeks. Since 2020, I am filling the tank about twice a year, instead of a couple of dozen times. I’m saving hundreds if not thousands of dollars because of that alone. My auto insurance also dropped dramatically when my mileage plummeted.
I wonder how many people have welcomed the changed to their lives like I have.
Lloyd—I’m with you. Frankly I haven’t minded trips to dr & dentists over the last 3 yrs because they have maintained very safe spaces. Anywhere else I wear an N-95, and I’ve managed to cut down on those visits hugely thanks to various types of delivery services. Local groceries here have online ordering service where you pick up outside (& it’s well-used—I’m not alone).
I finally rejoined my bookclub meetings in recent months–6 -9 people inside for 2 hrs, with several of us wearing N95’s. [And thank god they are friends, so when it came time for me to host my traditional annual poetry session, they were fine bowing to my covidparanoia with another zoom session– & all enjoyed it.] But have kissed off my choral groups for the duration — expelling that kind of air for 2 hrs straight is nuts, not to mention wearing masks while doing so is very unpleasant.
p.s., have kept in touch with my choral groups, & note that their attendance is regularly interrupted by people getting covid, warning others who sat near them, etc quarantines resembling what goes on in schools– & these are all seniors! Same thing happens with the several instruments bands my husband is in…
Not to mention that my millennial sons teach musical instruments, & since covid protocol was relaxed, both caught it once, & one a 2nd time just 6 wks ago. Plus I have a friend our age who is vaxxed & boosted but less than careful about masking/ exposure, who ended up in hospital last month with covid + pneumonia… paxlovid did the trick [+ 3 wks recovery]…
I worry about my sis, a 60yo asst hisch principal who is very careful but has an autoimmune disease that places her at high risk. Her one bout with it last yr was greatly relieved by paxlovid but took many weeks to recover. (So wish she would retire already.)
Glad you are still here to impart your wisdom and interesting stories, Lloyd.
And to tell it like is without any varnish.
One of the points in the Post that not enough attention has been paid to.
“For instance, Oster seemed to disregard about 20% of the U.S. population [who] lived in homes with at least two adult generations or grandparents and grandchildren under 25 in 2016, according to an analysis of census data by the Pew Research Center. And the dangers of spreading COVID from students to older family members was greater in low-income Black and Brown households.”
It was those multi generational households that got slammed in Lombardi Italy and in NYC. That 20% of households is not distributed equally among the States. Florida may have 3% more people over 65 than NY but there is a big difference between Grandma widowed or Grandma and Grandpa living in a gated Retirement Community a 1000 miles from children and Grand Children or living in the same Apartment, Apartment Building or Multi Family House. Especially in NYC’s immigrant communities. DeSatanist’s the mass murderer would have even greater deaths ,more than the 40,000 greater than NY. If the Villages et al. were multi generational communities.
Which brings us back to NYC. Cuomo made a good faith honest policy mistake returning recovering patients to Nursing Homes which were already experiencing rampant infections brought in by staff. However his _____ ego cost countless lives at the very start of the pandemic. deBlasio was no genius he was blackmailed by Dr. Oxiris Barbot the Cities Health Commissioner to close the Cities Schools when there had only been a few deaths but people were flooding emergency rooms. At a Cabinet meeting she threatened to resign and go to the press, her staff at the Health Dept. cheered when deBlasio made the announcement . Cuomo the second biggest narcissist in the Country turned around pounding his chest .
“He don’t close schools only I can close schools”
That 4 or 5 day period probably killed a huge number of Grandparents.
Right on, Joel. I remember reading that in poor communities, at least 50% of families live multigenerational.
Also remember looking at Boston-area school stats where a couple of [poor, POC] districts were experiencing MANY times the ave regional rate of cases, hospitalizations & mortality. Naturally, these were the 30% or so of total school pop who did not return to in-person schooling there and in many urbs [same thing in Providence CT where Cardona was working].
And in urbs where poor POC predominate [like DC], that is why pubschs did not return to in-person schooling for a very long time. [Rabid locals wanted to blame it on teachers unions—which is silly, because DC pubschs are 50% non-union charters… ]

The entire idea that schools which have been seen as incubators of infectious diseases yet somehow were not vectors to spread Covid was absurd on its face.
https://www.wsj.com/articles/child-covid-19-cases-rise-in-states-where-schools-opened-earliest-11630834201
It is not the child Covid cases which mostly were relatively mild, we hope, we don’t know long(!!!) term effects! It is how those infections were magnified in the community. We agree all communities are not the same. Corona/ Elmhurst or Borough Park multi generational high household density epicenters of the first NYC outbreaks are not the same as Suburban Connecticut or even Suburban NY or NJ. Neither are twenty story Apartment Buildings with one or two elevators and hundreds of tenants the same as 1 family houses in the burbs on a 1/2 acre of land.
Almost as absurd as that Mass Transit was not a vector. Perhaps in South Korea where everyone wore masks since SARS 1 and testing was real. If you were ever on a subway train in NYC at rush hour ,the only moving air is from the person standing and coughing a foot in front of your face.
The claim that a respiratory virus like SARSCov2 is not transmitted to any significant extent in schools doesn’t make sense, but it doesn’t have to.
Policy — even health policy — in the US is often not driven by rationality and common sense but by “economic sense “(sic and sick)
Anyone who doesn’t believe that should just look at the recent decision by Modern to raise tge price of their vaccine (which was developed and tested with OUR tax dollars!) from $26 to $130, which effectively means many people without insurance won’t get vaccinated or boosted.
Bernie Sanders has criticized it, but have Biden or CDC said a word about this? Not that I can find.
There was an article just last night on Long COVID on CNN. It’s estimated that 40 percent of young people experience Long COVID, even if they had a mild case. Most recover within a few months, but some do not.
We put a lot of people’s long term health on the line in the name of the economy, free baby sitting, and “freedom “
Many (perhaps even most?) people who
make counterintuitive or even nonsensical claims actually believe them.
Motivated reasoning is behind a lot of such stuff.
https://www.motherjones.com/politics/2011/04/denial-science-chris-mooney/
It’s actually a fascinating — albeit frightening — topic.
Frightening because It means that humans are actually only “homo self-deluding-sapiens”
Joel– Oh, yes, I lived in Manhattan & Bklyn nearly 20 yrs, commuting daily on subways. Can’t decide whether IRT or BMT was the worst for crowding, getting leaned over on/ coughed on [probably IRT]. F & RR in Bklyn were better, but I was headed downtown where there were incredible cheek-by-jowl crowds making their way to street level. Can’t imagine having done any of that during pandemic [tho I expect all that must have winnowed away to sparse travel then—you tell me]. Also relate to elevator travel at home and [worse] at work. Small wonder NYC was 1st epicenter, as Euro-NY flights brought the already-transmitted-from-China virus in (while all eyes were still on the NW).
Joel—yes, the 2020 pronouncements that in-person schools were not vectors were ludicrous [aided/abetted by Oster’s cherry-picked stats magnified in media]. Then Southern states promoting that nonsense doubled down by opening in-person colleges in summer 2021, ushering in the delta wave that moved South to North.
The problem was actually worse than cherry picked data.
It was a fundamental lack of understanding about what COVID test results mean — or more critically, might NOT mean.
Assuming that test positivities are an accurate indication of the infection rate , without taking into account the uncertainty of the results due to possible test false negatives is a fundamental error.
I commented on Osters lack of understanding — proved by her own words here
https://dianeravitch.net/2020/10/29/rachel-cohen-emily-oster-was-too-optimistic-about-children-and-covid/#comment-3130845
Schools were literally all over the place when it came to test protocols (tests performed, who got tested, how often, whether it was random, etc).
It’s simply ludicrous to assume that a “bare” (no uncertainty) test positivity rate provided by a school or district accurately indicates the actual infection rate.
And even with details, which are necessary for estimating test uncertainty, one MUST take test uncertainty into account, which necessarily means that quoting test positivity rates like 0.2% is just total BS because it implies far more accuracy than is possible with even the most accurate COVID test administered under the best circumstances (high viral load late in the infection)
By now, haven taken the rapid CoVID tests themselves, many people now realize just how INaccurate they can be.. My sister took a rapid test 3 times before she got a positive.
Whether you get a positive when you are infected is highly dependent on when you take the test during the progression of the infection. This is because the test sensitivity depends on viral load present.
Research has shown that some of the rapid tests can have false negative rates as high as 50%.
How many school districts were using the rapid tests because they are much cheaper than the more accurate PCR?
What does a quoted test positivity of even 2% mean if the test used to obtain that”result” had a possible false negative rate of 50%?
Nothing.
Not incidentally.
It wasn’t just economists who failed to take into account and report the uncertainty associated with test positivity results.
They may have fixed it, but John’s Hopkins was reporting “bare” test positivities for the different states with no attached uncertainty.
Its just pure bullshit to report scientific results without uncertainty.
